Privacy Policy
Last updated: December 1, 2025
Overview
At Percent-Calculator.io, we respect your privacy and are committed to protecting it. This policy explains what information we collect and how we use it.
Data We Do NOT Collect
All calculations happen in your browser. The numbers you enter into our calculators are processed locally on your device and are never sent to our servers. We have no way to see, store, or access your calculation inputs or results.
Local Storage
We use your browser's localStorage to store:
- Your cookie consent preferences
- Calculation history (if you use this feature)
This data never leaves your device. You can clear it at any time through your browser settings.
Analytics
With your consent, we use Google Analytics to understand how visitors use our site. This helps us improve the user experience. Google Analytics may collect:
- Pages visited and time spent
- Device type and browser
- General geographic location (country/city level)
- How you found our site
We have enabled IP anonymization, so your full IP address is never stored. Analytics only runs after you consent via our cookie banner.
Cookies We Use
| Cookie | Type | Purpose | Duration |
|---|---|---|---|
| cookie-consent | Necessary (localStorage) | Stores your cookie preferences | Permanent |

Your Cookie Choices
When you first visit our site, you'll see a cookie consent banner. You can:
- Accept all cookies
- Reject non-essential cookies
- Customize your preferences
You can change your preferences at any time by clearing your browser's cookies and localStorage, then revisiting the site.
Third-Party Services
We use Google Analytics, which is operated by Google LLC. Their privacy practices are governed by Google's Privacy Policy.
Your Rights (GDPR/CCPA)
Depending on your location, you may have the right to:
- Know what personal data we collect
- Request deletion of your data
- Opt out of analytics tracking
- Not be discriminated against for exercising these rights
Since we don't collect personal calculation data, most of these rights relate to analytics. You can opt out of analytics at any time via the cookie consent banner.
